INVENTOR WITNESSES I THEODORE E. CHARLBERG, OF MOLINE'ILLINOIS-scnnnn-rnsrnnizn.

Specification of Letters Patent.

Patented June 18, 1918.

Application filed August 10, 1917. Serial 110. 185,571.

To all whom it may concern:

Be it known that 1,,THEODORE E. CHARL- Bnne, a citizen of the UnitedStates, residing at Moline, in the county of Rock Island and .State ofIllinois, have invented new a (1 useful Improvements inScreen-Fasteners, of which the following is a specification.

This invention relates to screen fasteners and one of the ob'ects is torovide a device which may readily be attac ed to the side portions ofthe frame of a screen of usual construction, for the purpose ofpermitting the screen to be secured outside of a window sash, andwithout the necessity of using a ladder if the window to be screenedhappens to be in an upper story, and without the necessit of operatingfrom the outside of any win ow when lacing the screen in position andsecuring't e latter.

A further object is to, provide a device comprising a sheet metal blanksuitably cut and bent' into shape in order to provide for a main portionto be attached to the frame of the screen and a flanfed portion havingan engaging slot and a apted to pass over the shank portion of a screwor the like reviously placed in position in the win ow frame.

-With the foregoing and other objects in view, the invention consists inthe novel construction hereinafter described and claimed.

, In the drawings Figure 1 is a view of a full length screen inelevation showing my attachment applied thereto.

Fig. 2 is a further view in elevation showing the attachment applied tothe central portion of a smaller screen.

Fig. 3 is a view in. vertical section through a screen mountedinposition in the window frame, and showing also the upper and lowersash.

Fig. 4 is a perspective view of the attachment.

metal from which the fastening device is formed.

In carrying out my invention I provide a blank of sheet metal comprisinga main por- 60 tion 10 and a wing ortion 12 extending latorally from oneFig. 5 is a view of the blank of sheet ge thereof at about the centralportion of the main blank, said central portion being slottedlongitudinally and shown at 15 for the purpose of permitting screws orother engagmg devices to pass through the slot when securing thefastener to the side of the frame of a screen.

Portion 14, constituting the engaging member designed to be brought intocontact with a screw, pin, or other device connected with the frame-ofthe window, is bent along a line indicated by 16, said ortion 14 beingthen deflected at substantially right angles to member 10.

The upper end of member 10 may be curved or deflected with reference tothe main portion of the device, this curved portion being designated 17,and the edge 18 thereof being brought into position adjacent to one edgeof member 14, thus providing a cover portion acting as a protectingmember and preventing injury to the hands in manipulating V the screenor window sash and also affording means for manipulation.

The screws passing through the slot 15 are designated 20, and two ormore screws may be em loyed in suitable positions, the slot providmg foradjustment as desired,

after the screws have been inserted but not fully driven in, so thattheir heads will con tact with the surface of plates 10.

The fasteners constructed as described are applied to the side members24 and 25 of the frame of a window screen, and these fasteners are madein pairs in order that the members 14 may be properly ositioned withreference to the adjacent e ge of the a screen. These members 14 aresimilarly formed in each' instance but are merely located on oppositesides of the plate portion 10. The slots of members 14 are designated14. l

It is obvious that the device may also be employed for the purpose ofsecuring an extra or storm sash to the outer portion of a window frame,and that it may also be used for similar purposes in connecting adjacentelements which it is not desired to secure permanently.

I claim The combination with a frame of a screen and the vertical sidemembers thereof, of a V plurality of plate members secured to oppositesides of the frameon the inner surface thereof, said plate members beingeach provided with a flanged member having a slot 5 extending from theinteriorportion thereof to the outer edge, means carried by the frame ofa window for engaging said slots and a curved member eiztendin 7 fromthe end of the plate member and de ected from the main surface thereofover the flanged 10' portion to a point adjacent to the exposed edge andthe upper free corner thereof.v
